Application filed Apri1 12, 1928. Serial 1T0. 269,425.

My invention belongs to that general class -of devices known as fabrics and relates more particularly to a wire spring fabric for beds ther object the production of a fabric in which the top face thereof is substantially level or flush throughout the fabric. Many other ob- 'ects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists 1n the novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out 1n the claims.

In the drawings, wherein like reference characters indicate. like or corresponding parts:

Fig. 1 is a top plan view of a portion of a fabric embodying the invention;

Fig. 2 is an enlarged view of a portion of the same; Fig. 3 is a sectional view taken substantlal- 1y on line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken substantial- 1y on line 4-4 of Fig. 2;

Fig. 5 is a sectional view taken substantially' on line 5-5 of Fig. 2;

Fig. 6 is a sectional view taken substantially on line 6-6 of Fig. 2, Figs. 4 to 6, inclusive being on a further enlarged scale from that of Fig. 2.

Fig. 7 is a sectional view taken substantially on line 7 7 of Fig. 6; Fig. 8 is a view similar to Fig.7, illustrating a modified construction;

Fig. 9 is a sectional view taken substantial- 1y on line 9-9 of Fig. 8 and Fig. 10 is a .side elevation of a typical spring construction.

In the drawings, wherein I have illustrated the preferred embodiment of my invention, referring to Fig. 1, it may be mentioned that only a portion of a .bed s ring is shown for purposes of illustration. nthis figure 1'-1, etc., appears substantially as aseries of rings, but in the case of a bed spring these represent the ends of coiled springs, these usually being made substantially as shown in Fig. 10, in a series of spiral coils gradually contracting toward the center and thence enlarging again-so that the two ends really are spaced rings connected by a spiral spring portion. It is not necessary, however, to describe this in detail. My improved fabric particularly consists of a series of coil springs arranged within a suitable frame 6 at the top and bottom, the sprin members being connected to each other and to the frame. The-present invention relates more particularly to the means for tying or looking the several coil springs to each other or to the frame. As

shown, the several coils are connected by coil springs 2 and 3 of the desired size as to length and diameterand of such gauge of spring wire as to give the required tension. These springs are connected at the center by forcing one spring in between the coils of an adjacent spring without threading one into the coils of the other. The coils of one spring are, of course, spread as most clearl shown in Figs. 3 and 4, in which the coils o the spring 2 are spread to receive the coils of the spring 3. When so forced together, the coils of the spring 3 engage at the inner sides of the coils of spring 2, and the parts are maintained in engagement. They may be readily assembled in this manner, and when so assembled will under ordinary usage remain in; assembled relation. The end of each coil is con nected to the adjacent sprin 1. Referring particularly to Figs. 2, 6 and- 7, the ends of each'of the'springs 2 and 3 are provided with hooks 4 adapted to engage or ook on to the adjacent spring 1. However, if they were merely hooked over the springs 1, there would be a tendency for the same to slip sideways on the spring or possibly become-unhooked. To retain them in place and revent sliding, keepers 5 are provided. Ihese' are. merely short coiled springs which are slipped ver the spring 1 as shown, the coils being spread between the ends (see Fig. 7). When so arranged on the spring 1, they grip or clamp tightly on the same. The ends 4 of the coils are each hooked through the loops of the spring 5, as most clearly shown in Figs. 6 and 7, and then under the sprlng 1. Obviously, when the parts are so assembled, the ends 4. are locked on the springs 1 and prevented from accidental disengagement or from sliding, and at the same time the hooked end 4 passing through the coils of the keepers prevents these from slipping or becoming disengaged. When these are assembled the parts are locked together so that each spring 1 is locked to certain adjacent springs through various springs 2 and 3. It will be particularly noted in this construction that by so arranging the parts the top face of the spring, as well as the bottom face, preserves a substantially fiat level surface. The fabric is secured to the frame 6 by means of springs 7 which may hook over theadjacent springs 1 at one end and be secured thereto by the keepers 5 and at the opposite end 8 may hook over the frame part 6. However, in this instance similar keepers may be employed if so desired.

In the form shown in Figs. 8 and 9,11 rep resents the spring corresponding to the spring 1 and 12 a spring corresponding to springs 2 and 3. In this case, small spiral springs 13 instead of being slipped over the springs 1, are threaded on the same, and the ends 12' of the springs 2 and 3 are threaded through the springs 13. While this is a satisfactory construction, I generally prefer to construct the same as shown in Figs. 6 and 7.

It will be noted that in thp constructions described, not only is a flat or level surface secured, but that the several parts are locked together in such a manner that they will not slip or slide relative each other, and the assembling may be done without the aid of tools or machinery. It is not necessary to twist or bend the wires when the fabric is ing myself to the exact form, construction,

arrangement and combination of parts herein shown and descrlbed or uses mentloned.

What I claim as new anddesire to secure by I Letters Patent is:

1. In a fabric of the kind described, a series of springs, a plurality of connecting spring arranged between said first-mentioned springs, and means for securing the ends of said connecting springs to said first-mentioned springs consisting of a coiled keeper arranged on'the first-mentioned spring and engaging the same intermediate the coils of the keeper, said connecting springs extending through the coils of said keepers and back around the first-mentioned spring.

2. In a fabric provided with a plurality of spring members and in combination, means for tying said springs together consisting of a connecting member extending between adjacent springs, and means for securing said connectin member to a spring consisting of coiled springs slipped on said first-mentioned spring member and retained thereon by en-, gagement between its coils with the firstmentioned spring, said connecting member provided with a hooked end and threaded through said coil and engaging the first-mentioned spring.

3. In a device of the kind described and in combination, a ring member and a connecting member, said connecting member provided with a hooked end and overlying and underlying said ring member, and a keeper consisting of a coiled spring extending transversely of the ring and mounted thereon with the ring lying between adjacent coils of the spring, the hooked end of said connecting member threaded through said coiled spring whereby the keeper and connecting member cooperate and each one looks the cooperating member on the ring.

4. In a fabric of the kind described and in combination, a plurality of rings and resilient means for securing said rings together comprising coil springs, said coil springs having a hook at each end engaging one of said rings, and means for securing said coil springs to said rings comprising a pair of coils integrally connected to each other so as to be resiliently urged toward each other, said coils being arranged on said hooks and engaging said rings therebetween.

In testimony whereof, I have hereunto signed my name.
